Zinc Sulphate Monohydrate Plant

Zinc Sulphate Monohydrate is commonly known as Zinc Sulphate (ZnS04 H2O). Zinc Sulphate is a prime nutrient for plants. This micro-nutrient is primarily used in maintaining normal health and increased yields; The Zinc Sulphate is applied directly to the crops. It is also blended with other Fertilizers like SSP / GSSP etc. as it is required by plants in small quantity. Zinc sulphate monohydrate is very effective for treatment of different variety of crops such as cereals, pulses, oilseeds, cotton, sugarcane, vegetables, fruits, potato and many more.

Zinc Sulphate Product:

1. Zinc Sulphate Hepta Hydrate
2. Zinc Sulphate Monohydrate

Zinc Ash Specifications:

1. Zinc 70% (40 – 72%)
2. Lead (Pb) 8% max ( Lesser the better)
3. Iron (Fe) 5% max
4. Chlorides (Cl) 25 – 30 max (Less the better)

Manufacturing Process:

Water / Wash Water is filled in the Digester and Sulphuric acid is slowly added to the digester, While the quantity of Zinc ash is added slowly with agitation. The addition is continued till the completion of the reaction. As the reaction is complete the suspension is drained in the filtration tank for storage. The suspension is filtered with the filter press. The residue is washed and filtered again for better recovery. The filtrate is fed to the crystallizer. The cooling is provided by circulating chilled water from chilling plant. The solution is stirred continuously. As the required temperature is reached the Zinc Sulphate crystals separate out and the separated crystals are centrifuged with the help of centrifuge to remove any liquor remaining. For Zinc Sulphate Monohydrate the filtrate is dried in a spray drying system which is collected in a hopper and packed in bags to be sent to the market.
